The Effect of Pre-Endoscopy Maltodextrin Beverage on Gastric Residual Volume and Patient’s Well-being: A Randomised Controlled Trial

Abstract Background: Prolonged fasting prior to oesophagogastroduodenoscopy (OGDS) could be noxious to patients well-being. Aims: To determine the effect of maltodextrin beverage 2 hours before OGDS on gastric residual volume and patient’s well-being scores. Methods: A single-blinded, stratified randomised controlled trial was performed, comparing control group (A, received 400 ml of plain water) and carbohydrate loading group (B, received 400 ml of Carborie®) in terms of gastric residual volume (GRV) and patient’s well-being scores (visual analogue scale (VAS)) scores for hunger, thirst, anxiety, tiredness and general discomfort). Results: Of 80 randomised patients, 78 completed the study (38 received plain water and 40 Carborie®). The median (IQR) GRV was not significantly different between group A and B (5.0 ml (20) vs 4.0 ml (19)), p = 0.777). Both groups showed significant reduction in VAS scores in all five parameters ( p ≤ 0.001). There were no complications attributed to endoscopy in either group. Conclusions: Pre-endoscopy maltodextrin beverage is as safe as clear water with improved patient’s well-being in the intervention group.
